    Abstract: There is provided a method for producing a stencil for use in screen printing which method comprises coating a screen mesh with liquid photopolymerizable composition, imagewise exposing the coated mesh to radiation to polymerize liquid composition on the mesh in the exposed areas, and removing unexposed liquid composition from the mesh to develop the stencil. Suitably the liquid composition is applied with the screen mesh in contact with a protective film and, after imagewise exposure, the stencil is developed by stripping of the film such that unexposed liquid remains on the film. This provides a simple method of producing a stencil which does not require highly skilled personnel.

    Abstract: A method of manufacturing a water-release transfer is disclosed in which a design in a photopolymerizable ink is applied to a substrate having a water-soluble release coating and the design is subjected to photopolymerizing radiation, e.g. ultra-violet light, to cause the ink to polymerize to a solid state. Preferably the ink comprises a mixture of a liquid unsaturated monomer and a viscous or solid prepolymer, and one or both of the monomer and prepolymer contain acryloyl or methacryloyl groups. The invention includes water-release transfers manufactured using photopolymerizable inks.
